What about genealogy?
"As part of EPIC Ireland’s visitor experience, The Irish Family History Centre (operated by Eneclann) will be introducing an exciting way for visitors to search for their Irish ancestors, discover their own unique family story and explore Irish heritage. Knowing who you are and where you come from is something we feel everyone should get excited about. We want you to unearth your Irish roots in the most memorable way you can."Sounds like another reason for a first or return visit to Ireland.
